Harry an accidental Horcrux??

[Tandra]

No: HPFGUIDX 170638

I know, I know people feel this has been discussed to death, but I had
to toss my hat in the ring....

Let me try to verify my accidental making, though I know people think
it isn't possible because Slughorn said it takes a complicated piece
of magic to make one and so forth. But with Harry, and LV we are
dealing with magic that no one has seen. It basica;;y becomes a
guessing game for DD as he tries to figure out all the characteristics
of Harry's scar or what happened. 

So what's to say that if an AK is reflected that the person who cast
it doesn't lose a piece of their soul in the process. Maybe passing it
onto Harry through the scar very untintentionally. Isn't there a
theory that he entered the house with the intent to make his last
Horocrux anyway, so what's to say he hadn't already started said
complicated process before he got to the house and it was somehow
completed when the AK failed. 

Ok I've babbled on long enough...Feel free to tear it apart now.
